Puck Locks

Puck locks are the upgrade from a standard padlock that any serious trailer or storage security setup requires. Proven Locks' puck lock collection features a hidden shackle design that eliminates the most vulnerable part of a standard padlock — the exposed U-shaped loop a bolt cutter can grab in under three seconds. Instead, the lock body sits inside the hasp with no exposed shackle and no clean attack angle. Pair with a Proven hasp kit for a closed-shackle system built to hold up against the tools most commonly used in trailer and storage theft.

The most common tool in a trailer or container theft is a bolt cutter or angle grinder — and standard padlocks are specifically vulnerable to both. Puck locks are named for their round, flush body that gives attackers almost nothing to grip, grab, or cut.

• Hidden shackle design removes the #1 bolt cutter target
• Round flush body offers minimal attack surface for grinders
• Multiple lock core options: Cobra standard, disc-detainer upgrade, Medeco/Abloy available
• Designed for use with Proven hasp kits on trailers and containers
• American-made
• Free same-day shipping
